What do you think about the longitudinal NIH-funded Bogalusa Heart Study, created by cardiologist Gerald Bevenson in 1972? This study is following 16,000 who started in childhood and are now adults (40 years thus far). Researchers have looked at several things, on those living, as well as performing autopsies on 560 of these individuals who died since then (of accidental death or otherwise). 20% of autopsied children had plaques (fat deposits) in their coronary arteries, making this the first study of its kind to establish heart disease can exist in children, and those who were obese as children were likely to remain so in adulthood, as opposed to only 7% becoming obese who were not so in childhood.
